Brand new 2018 MacBook Pro battery dying quickly (Quick Fix)
I just got my hands on the 2018 MacBook Pro 15-inch (Maxed out at 2.9GHz Intel i9, 32GB Ram, Radeon 560X 4GB, etc).
I was starting to use the new 2018 MBP on battery mode… it was dying within 2-3 hours rather the stated “10 hours battery life”. I want the battery to cycle, but not that fast!!! After a bit of research and reviewing Activity Monitor’s Energy tab, it turns out that Google Chrome was the culprit (regardless of plugins). I’m assuming that if you’re reading this article then you’re reading it via Chrome.
Chrome forces the high performance GPU to run, but for good reasons within the webkit framework (i.e. better canvas 2D/3D rendering). However if one is on a battery I don’t think we care about better GPU performance. There is a setting to override this in Chrome’s internals, but if you’re like me you probably don’t want to be changing it every time you jump between AC/battery mode.
Fully exit Chrome, queue up Safari, and watch your battery time jump up to 8-10 hours. As a developer I use Google Chrome 99.9% of the time. The developer tools are just better in every way possible. For the sake of usability and life, Apple wins this round with Safari.
